recommendations! Published in 2017 at "Environmental Science and Pollution Research"

DOI: 10.1007/s11356-017-8493-8

Abstract: Mechanisms for removal of anionic surfactant sodium dodecyl benzene sulfonate (SDBS) in wastewaters by zero-valent iron (ZVI) were systematically examined. The contributions of four removal mechanisms, i.e., reductive degradation, oxidative degradation, adsorption, and precipitation, changed… read more here.
